Hi Now, I when I working on plpgsql_check, I have to check function parameters. I can use fn_vargargnos and out_param_varno for list of arguments and related varno(s). when I detect some issue, I am using refname. It is not too nice now, because these refnames are $ based. Long names are alias only. There are not a possibility to find related alias.
So, my proposal. Now, we can use names as refname of parameter variable. $ based name can be used as alias. From user perspective there are not any change. Comments, notes? Regards Pavel
